The Matt Helm movies were fabulous,
The Silencers,
Murderer's Row,
The Ambushers, and
The Wrecking Crew. Where Bond movies focused on the idea of 'For God and Country', Helm's attitude was a lot closer to 'For Dames and Whisky'. All in all a very enjoyable series.
Dollar for Dollar though, I find that the Flint movies are much more Cult-esque. Also submitted for your perusal, Nightbreed, an oft-overlooked Clive Barker vehicle that never got the sequel it needed.
Enjoy.
